-Please kindly note. Not quite. We use either 'kindly' or 'please', not both. They serve the same purpose, so we don't use them together. You can say either "Please note...." or "Kindly note..." -Please be informed. OK, but probably less usual. -Please kindly be noted. No. This doesn't make grammatical sense. Please note (!) that all of these phrases serve to introduce information. For example, you would say "Please note that that company website will be closed for maintenance from 10 am today." You wouldn't use them at the end of the email, or before you give the notification. If this is an important email, I suggest you post the whole email ( or at the least the main parts of it) for checking. If it's long, you should put it in the Notebook section.
